Battery modules are charged and discharged to SOC
Three different wirings tested:
V1: all 4 modules in parallel, one pair of wires on the first, one pair of wires on the last
V2: Modules 1+2 in parallel, modules 3+4 in parallel, two pairs of cables, DC+ on the first module, DC- on the second
V3: all 4 modules in parallel, one pair of cables, DC+ on the first module, DC- on the last
Residual capacity of the US2000C diverges in all of them.
The behavior could be reproduced several times.
